[This review was collected as part of a promotion.] I really wanted to like this shampoo but unfortunately my fine and color-treated hair did not respond well to it. I have dark brown hair and this brought out a ton of red in my hair. It also made it super oily after not even a day (I can usually go 2-3 days without washing with other shampoos). It does smell great and made my hair super soft! If you have medium to thick hair that isn’t color treated I would definitely recommend trying this!

this brand in general is amzing. i love how affordable and how its sulfate and paraben free. it makes my hair feel amazing clean and soft and i have color treated hair and this works amazing on my hair. i use to have very brittle hair and these shampoos made my hair soft its taking time but its doing its job i love ogx products!

I bought this a yesterday and washed my hair with it once!!! Seriously just once!!! And I had 4 clumps of hair fall out!!! Now my hair is dry and brittle!! The slightest tug an my hair comes out!!! Never ever get this I tried the damage remedy before this and it made my hair dry I've never used such a horrible product!!!!!

At first, I really liked this shampoo and conditioner. It smells great and left my hair super soft. After a while, I started to notice that instead of my hair growing stronger and thicker, it was actually starting to shed faster and fall out more. I was a bit upset because I loved the way my hair felt after using it! I'm not sure if anyone has had a similar experience but - other than that I really liked it and I wish I could have kept using it!

Hands down the best conditioner I have used. I’ve had trouble combing my hair Ever since I bleached my hair and dyed it. This conditioner leaves my hair soft and easy to comb. It doesn’t get tangly and I don’t have to deal with ripping my hair out while combing it. My hair also doesn’t look dry thanks to this conditioner. I LOVE this and HIGHLY recommend this. I always buy 2-3 at a time. Ogx Thick Full Biotin Collagen Shampoo 254 Oz Pack Of 2

This is my absolute favorite so far. I have noticed a difference in my hair volume and strength. I recommended this to some friends and family, and some of them now use it regularly as well. I am extremely satisfied with this shampoo, and an added bonus is that it is natural and also cruelty free. This product is worth every star!

I have a lot of fine hair, that can sometimes have the appearance of being thin since it is very fine. So I try to look for products that will volumize whenever possible! This product is really cost effective, and, in my experience, does have a positive impact on volumizing hair. The texture is somewhere in the middle of thick and runny, and smells absolutely amazing! I use it like a leave in and try to air dry whenever possible. This is a great go-to product for when I am looking for something that will get the job done at a more reasonable cost.

This shampoo smells amazing. The consistency is thick so a little goes a long way. the color of it is lilac which is also something I like. It makes my hair feel healthy and it deep conditions it whenever I use the conditioner. it isn't expensive and is a great product

I love OGX because it washes well and it doesn’t dry out my hair. This shampoo lathers very minimally but it’s a good thing. I found that shampoos that lather too much dry and strip your hair of natural oils. The smell of this Biotin and Collagen is great! Your hair will feel healthy after using it. The product is thick and it your hair will smell and look great. I highly recommend OGX products.

Do you have thin hair and want to change that? I have been using this for a year and I have definitely seen growth in my hair an the thickness of it! You can get this at your local store and adding the conditioner with it is amazing too. Smells great!!
